B. Refrigerant Connections
The refrigerant connections are shown in Figure 3. Each connection is 5/8 inch OD copper tube.
The refrigerant line connections are brazed as follows:
1. Clean and deburr the copper stub outs and the field supplied fittings that will make the
connections from the refrigeration system.
2. Use 15% silver brazing alloy to seal the refrigeration connections.
3. Make provisions to use the nitrogen brazing technique as described below to braze the
refrigerant joints.
4. Before brazing the refrigerant joints, protect the SWAGLOK
®
fittings illustrated in Figure 3 by
wrapping each joint with a wet cloth, and further protect it from direct torch flame with an
inflammable shield as shown in Figures 4, 5 and 6.
